Describe the contribution

Expected behavior changes

Additional context

  • Considering if 100 milliseconds would be better than 1000 to save time and have a print.
  • Considering fflush(stdout) instead of OS_TaskDelay

This has come up a time or two, the root of the problem is really that OS_printf is now always associated with a background task/local OSAL bufffer to do the output. This makes it so its always buffered consistently across platforms.

The price of that consistency, is that in previous versions, OS_printf on POSIX was just directly going to the libc printf, but now it's got an extra buffer in the middle.

Rather than adding a blanket delay - which is not ideal as its much longer than it really needs to be, while also not even guaranteeing that the output was flushed - since this is the PC-Linux PSP, and therefore known to be running on this platform, we should be using some form of perror here, or at least converting to fprintf(stderr, ....

Note that stderr stream is unbuffered, so there should not be any problem with immediately calling exit() afterwards.

jphickey commented Sep 1, 2021

Another option/suggestion would be to use the CFE_PSP_Panic function instead of exiting immediately from here. It's not much better as it stands (it still just does an abort, does not flush the OS_printf queue either) but at least it could provide a single point for doing so, rather than sprinkling OS_TaskDelay everywhere.

jphickey commented Sep 1, 2021

Also note that if we are touching these error message, I would like to see it report the actual errno in some form (at least the number, but preferably the string as obtained from strerror() or perror()). These error messages as they stand are too vague to be useful. While I realize this wasn't part of the original bug, this would be a good improvement IMO if we are touching the lines anyway.

FYI: I wrote issue #302 so as to not forget about this, it doesn't have to be part of this PR necessarily.

I like the CFE_PSP_Panic suggestion to replace the OS_TaskDelay and exit.

Ok, thanks for all the information. I have now used CFE_PSP_Panic as well as perror to handle the error.
Perror should now do an output in the following format: ": "
Does this meet your requested changes?

Changes look good!

Only required cleanup now is to squash down the multiple commits and rewrite the log message for merging.

Ok, great.

Only required cleanup now is to squash down the multiple commits and rewrite the log message for merging.

Of course, it is already done. I will push it right away.
